During the season premiere of "Teen Mom 2," Nathan learns that he has to spend 30 days behind bars in order to dismiss a felony charge against him. And he deals with the news in a way that doesn't please Jenelle: by drinking.

In the sneak peek below, Jenelle asks an intoxicated Nathan if he thinks he has a problem with alcohol.

"Do you think I do?" counters the young dad, who's facing the jail time as part of a plea deal involving a misdemeanor and other minor ordinances.

"I just think that when you do drink, you [just] binge drink," she explains. "Like you drink too much."

Nathan admits that he makes "poor decisions" when he has an excessive amount of liquor, but he grows more upset after Jenelle accuses him of drinking at "weird times."

"Like, you'll drink in the middle of the day and not give a f--k," she explains. After he asks the last time he did so, and her simple reply is "today," Nathan raises his voice and declares he doesn't "need to drink."

"Why are you getting offensive?" Jenelle questions.

"I'm not," he says. "You're sounding like you just said I didn't have an alcohol problem, but now you're saying that maybe you do. You know, I'm f—king done," he exclaims as he slams the door to their bedroom.
